Pavement surface texture and its skid resistance are two key safety parameters of highways, which both are influenced by pavement characteristics. This research is done on a newly constructed asphalt pavement (Qom-Garmsar freeway) in Iran. The goal is investigating the relation between skid resistance and pavement texture in order to asphalt content changes in Hot Mix Asphalt. Mean Texture Dept...

Background: Absent adaptive, individualized dose-finding in early-phase oncology trials, subsequent registration trials risk suboptimal dosing that compromises statistical power and lowers the probability of technical success (PTS) for the investigational drug. While much methodological progress has been made toward adaptive dose-finding, and quantitative modeling of dose-response relationships...

Body fluids and tissues in 16 methadone (MTD)-associated fatalities were investigated to find out whether analysis of MTD and its metabolite 2-ethylidine-1,5-dimethyl-3,3-diphenylpyrrolidine (EDDP) following enantioselective separation of both compounds may assist in the interpretation of MTD findings. Individual case histories were shortly described. R- and S-MTD as well as R- and S-EDDP conce...

Phase I trials are increasingly including dose-expansion cohorts after the maximum-tolerated dose (MTD) has been reached to better characterize the toxicity profile or identify early signs of efficacy within a specific disease population. This article provides guidelines on how to monitor safety and re-evaluate the MTD using data obtained from expansion cohorts of phase I protocols. We illustra...

Introduction: Patients with muscle tension dysphonia (MTD) suffer from several physical discomforts in their vocal tract. However, few studies have examined the effects of voice therapy (VT) on the vocal tract discomfort (VTD) in patients with voice disorders. Therefore, the aim of the present study was to investigate the effects of VT on the VTD in patients with MTD.   Materi...

We have identified and characterized Mtd, a novel regulator of apoptosis. Sequence analysis revealed that Mtd is a member of the Bcl-2 family of proteins containing conserved BH1, BH2, BH3, and BH4 regions and a carboxyl-terminal hydrophobic domain. In adult tissues, Mtd mRNA was predominantly detected in the brain, liver, and lymphoid tissues, while in the embryo Mtd mRNA was detected in the l...

BACKGROUND The utility of Mycobacterium tuberculosis direct nucleic acid amplification testing (MTD) for pulmonary tuberculosis disease diagnosis in the United States has not been well described. METHODS We analyzed a retrospective cohort of reported patients with suspected active pulmonary tuberculosis in 2008-2010 from Georgia, Hawaii, Maryland, and Massachusetts to assess MTD use, effectiv...

Recent research has proposed a moving target defense (MTD) approach that actively changes transmission line susceptance to preclude stealthy false data injection (FDI) attacks against the state estimation of a smart grid. However, existing studies were often conducted under a weak adversarial setting, in that they ignore the possibility that alert attackers can also try to detect the activation...

OBJECTIVE To quantify the correlation between gestational age and the normal distance between the insertion of the medial leaflets of the mitral valve and tricuspid valve in Thai fetuses. MATERIAL AND METHOD A prospective study was constructed using an apical 4-chamber view at end diastole to measure the mitral valve-tricuspid valve distance (MTD) in 169 confirmed-dated singleton normal fetus...

We present two model-based methods for learning Granger causality networks for multivariate categorical time series. Our first proposal is based on the mixture transition distribution (MTD) model. Traditionally, MTD is plagued by a nonconvex objective, non-identifiability, and presence of many local optima. To circumvent these problems, we recast inference in the MTD as a convex problem. The ne...
